The mouse I have been working on up until now has been quite a complicated design as it was the technical part of my MEng Cybernetics degree. So now that’s all over its time to make things a bit simpler and aim a little lower – this is after all a hobby and I can’t devote all my time to it as I once did.

So new electronics time I think, I am going to keep the chassis and just work on my ESD and layout. I think I will keep with the two processor design as I have a couple of DSP related things I want to try with the sensors and it requires quite a lot of processor grunt to get that going. The drive electronics will stay the same, no switched mode power supplies this time, and only sensors on the front. Oh and I will keep the bluetooth – why not!

I need to design new skids as the current ones require the lower sensor pcb of the old design, so its back to Solidworks and another order to shapeways for parts. And finally – need to find some nice batteries; the ones I am using are too big and a little under capacity.

Back soon with schematic…
